Persistent hallucinosis in borderline personality disorder.

A case series of 10 patients with a diagnosis of borderline personality disorder (BPD) presenting with auditory hallucinosis is examined. In this series, the hallucinations were persistent, longstanding, and a significant source of distress and disability. Extrapolating from this series to our sample of 171 patients with BPD suggests that a form of auditory hallucinosis may occur in almost 30% of this population.
